Industry-sponsored research payments (hereafter research payments) play an important role in the advancement of the medical sciences. Recent analysis of the Open Payments program (OPP) demonstrated that research payments are increasingly dispersed through noncovered entities (NCEs) across specialties. It is unknown how research payments are distributed to radiologists. The aims of this study were to assess trends in research payments to radiologists between 2015 and 2024 and to characterize paym…

ACR Appropriateness Criteria® Hematospermia
Hematospermia is an uncommon source of referral for imaging. When considering the adequate modalities for its evaluation, the patient’s age, duration, and associated symptomatology need to be taken into consideration. Younger patients with transient hematospermia and without associated signs or symptoms usually require a clinical approach and reassurance. In the setting of symptomatic hematospermia, persistent hematospermia, and in older patients, imaging may be indicated to assess for possible …

ACR Appropriateness Criteria® Management of Acute Pulmonary Embolism
Acute pulmonary embolism (PE) is a subclass of venous thromboembolism, which can be associated with significant morbidity and mortality. Risk stratification algorithms classify PE into high-risk (massive), intermediate-risk (submassive), and low-risk groups, with management guidelines determined based on clinical risk. For high-risk PE, first-line treatment options may include anticoagulation, systemic thrombolysis, catheter-directed therapies, and surgical embolectomy. For intermediate-risk PE,…

ACR Appropriateness Criteria® Male Breast Cancer Screening
Breast cancer screening recommendations have been established historically for women, but, have been less clearly outlined for men. For average-risk men and younger men less than 25 year of age, imaging is not usually appropriate as a screening test for breast cancer. For men of higher-than-average risk, screening with mammography as annual surveillance imaging is usually appropriate.The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical co…

ACR Appropriateness Criteria® Acute Left Upper Quadrant Pain
Acute abdominal pain is one of the most common chief complaints encountered in the emergency department and outpatient setting. Across all sites, the left upper quadrant (LUQ) is the least common location for abdominal pain with reportedly the lowest physical examination interrater agreement. The limited sensitivity of physical examination, combined with an uncommon and nonspecific clinical presentation, make assessment of LUQ pain challenging. Acute LUQ pain may arise directly from the spleen o…

ACR Appropriateness Criteria® Staging and Disease Monitoring of Rectal Cancer
In rectal cancer, because of the need for high-resolution anatomic detail in determining local tumor extension, imaging for local staging and restaging of the primary tumor in the pelvis is considered separately from the evaluation of distant metastatic disease in the chest, abdomen, and pelvis, often resulting in the need for a combination of modalities to fully stage the patient.The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical condi…

ACR Appropriateness Criteria® Staging and Disease Monitoring of Colon Cancer and Appendiceal Cancer
The role of imaging in initial staging of colon cancer, and in posttreatment restaging or surveillance, is most beneficial in identifying distant metastases in the chest, abdomen, and pelvis, regardless of primary T or N stage. Appendiceal cancers are classified separately and managed differently than colon cancer; however, initial staging and postoperative surveillance is also primarily focused on detection of distant metastatic disease, usually in the abdomen and pelvis.The American College of…

ACR Appropriateness Criteria® Staging and Follow-Up of Ovarian Cancer: 2025 Update
Ovarian cancer remains the sixth most common cause of cancer mortality in women in the United States and is a leading cause of mortality among patients with gynecologic malignancies. Imaging plays an important role in pretreatment staging of epithelial ovarian cancers, the evaluation of posttreatment response, and follow-up. Accurate pretreatment imaging is integral to determine appropriate first-line therapy. By delineating the extent of disease, imaging can assist decision making regarding the…
